A jet engine in which air intake and combustion occur intermittently, producing rapid periodic bursts of thrust.
(Aeronautics) a type of ramjet engine in which air is admitted through movable vanes that are closed by the pressure resulting from each intermittent explosion of the fuel in the combustion chamber, thus causing a pulsating thrust. Also called: pulsejet engine or pulsojet
a jet engine in which combustion occurs intermittently, owing to the opening and shutting of flap valves at the air intake.
A jet-propulsion engine containing neither compressor nor turbine. Equipped with valves in the front which open and shut, it takes in air to create thrust in rapid periodic bursts rather than continuously.
